Specification of Letters Patent.

Patented July il,

Application filed ebruary 6, 1914. Serial N o. 816,880.

citizen of theUnited States, residing in theY city of Newark, county of `Essex, and State of New Jersey, have invented certain new and useful improvements in Pen-Clips, of which the following is a s pecilicat'ion.

My invention relates to improvements in spring clips for holding pencils, pens, thermometers and the like in the pocket and the invention particularly resides in the means for fastening the clip to the article.

It is of primary importance to make such artic es as reservoir pencils, fountain pens and the like with a minimumdiameter or thickness and at the same time to provide as large a space therein as possible in order to accommodate the inserts, such as the pencil feeding devices, and ink reservoirs, With the largest possible capacity so that there is but little, if any, available space for the fastening ot the clip. has, been suggested to fasten the clip entirely-7 oii the outside of the articleas by means er an encircling spring band, but this has the disadvantage of working loose and is seldom secure in position. Where the fastening means ci' the clip eX- tended through the outer wall yoia the article, the projections therein liaifey either reduced the possible diameter of the insert or formed a projection which caught the end of the insert'as it was positioned in the casing or barrel.

@ne or' the objects of the invention is to securelyv fasten the spring clip in position' on the article so as not to appreciably increase the possible diameter.

As these articles are frequently made ot' one 4or" the precious metals, the casings are usually made of very thinly rolled metal and accordingly it is a further object of the invention tofsecurely fasten the clip to this thin material without the use of. any reinforcement to take up torsional strains.

Various other objects and advantages of theinvention will be in part obvious from an inspection of the accompanying drawings and in part w'll be more fully Lset iorth in the following particular description of one forni of mechanism embodying the invention and the invention further consists in certain new and novel features of construction and combination of parts hereinafter set forth and claimed. n

Referring to the accompanying drawings:

Alixed to the barrel clip Ll which may be of any of the conveni nt designs, comprising a free end 5 for engagement with the pocket and a relatively broad base 6 conforming substantially to and fitting the curyature of the barrel. A prong I extends from the end of lthe base `6 and is bent .transversely anglo to the length of the clip. A second prong S is cut from the base G and bent therefrom parallel to the prong leaving an aperture 9 centrally in the base t5. By means of v suitable stamps a portion of the initialof the barrel l is pressed outward to forni an internal recess l0 oase 6 is laid barrel i'ith the prongs inserted respectively in slots ll and l2 and by means of a closely littiiig mandrel the inner ends of tlie prongs are pressed longitudinally leaving the interior of the projections. the actiono this rod tends to bulge the metal of the barrel strains tais point.

It isofcourse obvious in those cases where the barrel is made of some relatively thick' "2-material as rubber compound shownin Fig. -5, that the recessl() may be formed by suit-l ably milling the" inner wall of the bore withmout pressing the material Aoutward Aand there 11s 'thus maintained the uniformity of con- ',fguration tothe outside of the barrel and athe inner bore is freed of any projections.

Having thus described my invention, I

I i claim:

l portion, of an integral clip having a pocket engaglng free end 4and means adjacent the other end for fastening the same to the bar-- rel at the recessed portion thereof, said means including angled prongs extending -..25 ..through said 'slots with the ends thereof dis- 'p0sed entirely within said recess, whereby Itl-ieboreof the barrel is free of any projection.

2. In a device of the class described, the 3Q combination with a .barrel having a slot rtherein, of a clip having 'an opening therein and a prong adjacent said opening posit'ioned in said slot, a` portion of said prong being pressed against said barrel'and a por- ,tion of said barrel pressed within said opening to hold said barrel in engagement with said clip. j

`i 3. In a device of the class described, the ""'mbination' of a tubular barrel of rela- A yiform cross-section adapted to contain an 'ji'nsert havlng a cross-section equal to that of the bore and a clip having parts extending through saidbarrel and engaging the' same on the inner side-thereof.

. 4. The combination with a barrel of a 'fountain pen having a raised portion forming a recess within Ythe barrel, said portion l"having a plurality of apertures therea0 through, of a unitary spring clip having means integral therewith adjacent one end thereof for fastening the same to the outside of the barrel, said means comprising a flexible prong adjacent the fastened end of the in one of said apertures and a second prong bent from the clip intermediate its sides and upset in another of lsaid apertures, the port-ion of said prongs within thev barrel being within saldjrecess 6o whereby. projections within said barrel are Y* eliminated.

vely thin-metal having an inner bore of` tiene.; l

5. The combination with a tubular barrel of relatively small bore having a portion adapted to'have a clip a'fxed thereto, said portion havmg a plurality of apertures eX- tending therethrough, of a unitary spring tened end -of the clip and upset in one of said apertures and a 'second rong bent from the clip intermediate its si es `and upset in another of said apertures, said prongs both extending in the same direction and rmly engaging the inner surface of the barrel to reinforce the portion thereof having the apertures.

' '6. In a device of the class described, the combination with a tubular member having a pair of spaced apart apertures therein, of a one-piece sheet-metal clip relatively -thin compared to its other dimensions, said clip having a relatively broad base portion adapted to conform to the outside of the member adjacent the apertures and having a pocket engaging portion forming a substantially straight prolongation of said base,

with a portion thereof adjacent the base n adapted to be spaced from the adjacent portion of the member to form a space therebetween, said base having a plurality of prongs integral therewith and `bent therefrom, one for each aperture, the distance between the bent prongs being substantially equal to the distance between adjacent edges lof the apertures, said prongs extending through the apertures, having a tight fit therein and adapted to be bent within the member to fasten the clip in position.

7 A pen clip forming an article of manufacture adapted to be fastened to a fountain pen barrel, said clip comprising a one-piece sheet of spring metal relatively thin compared with its other dimensions having a base adapted to conform tothe configuration of the outer surface of the barrel and having a pocket engaging member forming a substantially straight prolongation of said base, said base portion having a plurality of prongs integral therewith and adapted to be bent from the general plane of the base and pocket engaging member to fasten the clip to the pen barrel, one olf said prongs being an extension from an outer edge of said base.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
